World War One German Albatros DVa
From the web-site: A model D.IV had been developed with a more rounded fuselage compared with the earlier models which were flat sided. The D.IV also featured a return to D.II style equal chord wings however performance was uninspiring and the engine installation gave trouble so the model was not pursued although its fuselage was retained for the D.V series which returned to the ‘V’ strut wing layout. Some structural problems encountered by the D.III persisted with the D.V however the D.Va introduced heavier spars and visible steel tube braces between the lower front strut and the leading edge of the lower wing and this helped considerably although it did not eliminate the problem completely in some elements of combat flying. Over 4,600 Albatros D series fighting scouts were built of which just two survive today, both D.Va’s and these are to be found at the National Air and Space Museum in Washington D.C. and at the Australian War Memorial, Canberra.
